Append-only project lesson log at .cleargate/FLASHCARD.md. Use BEFORE starting non-trivial work to read past gotchas ("check" mode). Use WHEN you (a) hit a surprise, (b) found the winning path after a non-trivial task succeeded, or (c) were corrected by the user — record a one-liner for future agents ("record: <text>" mode). One-liners only; tag with #schema/#auth/#test-harness/etc. Also triggers on phrases: "turns out", "unexpected", "gotcha", "wasted time on", "starting work on", "before implementing", "user pushed back", "prefer X over Y", "winning path", "after several attempts", "the recipe that worked".
